Unveiling the dominant gas heating mechanism in local LIRGs and ULIRGs
Miguel A. Perez-Torres, Antxon Alberdi, Cristina Romero-Canizales +5
We show preliminary results from a sample of Luminous and Ultra-Luminous Infrared Galaxies (LIRGs and ULIRGs, respectively) in the local universe, obtained from observations using…
EVN observations of the Ultra Luminous Infrared Galaxies IRAS 23365+3604 and IRAS 07251-0248
Cristina Romero-Cañizales, Miguel Ángel Pérez-Torres, Antxon Alberdi
We present high-sensitivity, high-resolution images of the Ultraluminous Infrared Galaxies (ULIRG; L L) IRAS 23365+3604 and IRAS 07251-0248, take…
Emission line activity in type 2 quasars from the Sloan Digital Sky Survey
Montse Villar-Martin, Andrew Humphrey, Alejo Martinez-Sansigre +3
We have compared the optical emission line ratios of type 2 quasars from Zakamska et al. with standard AGN photoionization model predictions, Seyfert 2s, HII galaxies, and narrow l…
The jet of Markarian 501 from millions of Schwarzschild radii down to a few hundreds
M. Giroletti, G. Giovannini, W. D. Cotton +4
Aims: The TeV BL Lac object Markarian 501 is a complex, core dominated radio source, with a one sided, twisting jet on parsec scales. In the present work, we attempt to extend our…
Absolute kinematics of radio source components in the complete S5 polar cap sample. III. First wide-field high-precision astrometry at 15.4 GHz
I. Marti-Vidal, J. M. Marcaide, J. C. Guirado +2
We report on the first wide-field, high-precision astrometric analysis of the 13 extragalactic radio sources of the complete S5 polar cap sample at 15.4 GHz. We describe new algori…
